Application filed .1 anuary 29, 1917. Serial No. 145,090.

To all whom it may concern:

Be it known that l, PASCAL Noon, a citizen of the United States, residing at the city and county of San Francisco and State of California, have invented new and useful Improvements in Sanitary Syrupers and Fillers, of which the following is a. speciand, furthermore, to provide means for auto-. matically closing the valves-the moment a predetermined syruplevel is reached within the cans, said automatic operation taking place regardless of the can contents when received bv the syruper. Further objects will hereinafter appear. 1

The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which suitable manner.

Figure 1 is a plan view, partly in section, showing the sanitary syruper and filler.

Fig. 2 is a side elevation of same, partly in section.

Fig. 3 is a central, vertical section of one of the syrup charging valves.

Referring to the drawings in detail, A indicates a suitable supporting frame in which is journaled a vertically positioned driving shaft 2, to which a continuous revolving movement is transmitted in any Secured to the shaft is a circular, can-receiving table 4, in which is mounted a plurality of reciprocating plungers5. Secured on the shaft, below the canreceiving table, is a circularguide plate 6 through which the lower ends of the plungers5 extend. Formed on the upper surface of the frame A is a circular cam track,

on which is formed two raised sections 4 and 8; and journaled in the lower end of each plunger is a roller 9 which is adapted gers, as will hereinafter be described.

Secured on the shaft, above the can-receiving table, is a hub member 10, upon which is formed a plurality of horizontal, radially disposed arms 11, the outer ends of which are enlarged to form semicircular recesses or pockets 12 for the reception of cans, such as indicated at 13. Secured on the shaft, above the arms 11, is a spider ring 14., to whichis secured a plurality of syrup-charging valves, generally indicated to engage the cam track and raise the plunat 15. lFhe present machine is provided with eight syrup-charging'valves 15 and eight arms 14; the recessed ends of said 'arms being positioned in direct alinement with the syrup-dispensing valves to permit a perfect register of each can delivered.

The construction of the syrup-dispensing valve, together with the means for delivering syrup thereto without exposing the syrup to air or contamination in any manner, is one of the most important features of the present invention. This is accomplished as follows: Referring to Fig. 3, 16 indicates a tubular member of considerable length, having projections 17, to permit it to be secured to the spider ring 14. Secured in the upper end of the tube 16 is a hollow head member 18, the lower end of which is extend ed and reduced in diameter to form a seat for a flexible rubber tube 19. Extending cen-.

trally through the head 18 and the tube 16 is a vent pipe 21, on the lower end of which is secured a disk 22,- which will hereinafter be known as the stationary valve seat. Interposed between the stationary valve seat and the lower end of the tube 16 is a disk valve 23, which is provided with a hollow hub extension 24 entering the tube 16. The upper end of this hub extension is reduced in diameter in a manner similar to the lower 1 end of the head to receive the lower end of the rubber tube 19 and also to receive a surrounding coil spring 25 which. normally holds the valve 23 against the seat 22.

The disk valve 23 is considerably larger in diameter than the can which it covers while charging. llts lower face is provided with a rubber disk 26, which not only serves to form a seal between the valve 23 and the can while charging is taking place, but also serves the function of providing a ti ht connection between the stationary va ve seat and the disk 23 when engagement is made iii therewith. The stationary valve seat is provided with a plurality of radial openings 27 which communicate with the vent pipe,

and the upper end of the vent pipe is provided with a coupling 28 in which is secured a hollow plug 29. Formed on the lower end of said plug is a valve seat, and extending through the plug and practically through the whole length of the vent pipe is a rod 30 which carries a float 31 on its lower end ply by means of pipes 34; these pipes being secured at their lower ends to each indi-- vidual valve and at their upper ends to a' manifold or central distributing head 35 which revolves about a stationary syrup deiivering pipe 36 which is connected with a source of supply, such as a tank or other means not here shown.

In actual operation, practically any canfeeding mechanism may be providedfor the purpose of delivering the cans in successive order to the table i. lln the present instance a star wheel 40 has been provided, This revolves at such a speed that it will deliver a can to the outer end of each arm 11 as these, together with the table, are revolving. Each can delivered will assume" a position centrally with relation to a plunger 5 at the point indicated at G. The cam willhere travel in unison with the table, the plunger and the engaging arm to a point where it strikes the first raise 7 of the circular cam track 7. This raises the upper edge of the can into engagement with thelower rubber lined face 26 of'the valve 23 carried by an alined charging valve. A further movement causes the plunger to engage the higher cam portion 8 and forces the valve 23 away from its stationary valve seat 22. Syrup from the pipe 36 passing through the manifold and pipe 34 1s, therefore, permitted to pass through the hollow head 18, the flexi- -ble rubber tube 19 and the central hollow portion of the hub extension 24: of the valve and will flow between the valve 23 and the stationary valve seat directly into the can, a perfect seal between the valve 23 and the can being maintained by the disk 26. The syru would continue entering the can and backing up through the vent pipe 21 as long as the plunger is in engagement with-- the high portion of the cam 8. This is, however, prevented in the present instance by providing the float 31., This will iedi= a predetermined level regardless of the contents of the can when received, A uniform filling. and weight is obtained when the syrup-charging operation is completed; the length of the high portion of the cam 8being such that practically any amount of syrup required'may be permitted to enter the can during the charging period. A. continued revolving movement causes the roller I I on the plunger to leave the cam and return to normal level. This first permits the valve 23 to engage the stationary valve seat, thus shutting off the syrup supply, and also permits the can to move away from the valve to a point where it may be freely discharged, as indicated, by the arms 50.

' The radially disposed passages 27, formed in the stationary valve seat, are of considerable importance as they permit a free venting action while the syrup is flowing into the can and also prevent any trapping of air in the annular passage formed between the stationary valve seat and the can, as

shown in Fig. 3. v

The flexible rubber tube is also an important feature'as it forms a positive connection capable of being extended or compressed when the valve 23 is raised or lowered. Any syrup is, therefore, prevented from leaking out between the tube 16 and the hub extension 24 of the valve, thus preventing sticking or gumming up of the valve which might interfere with moving parts. The spring 25 has sufficient tension .to maintain a perfect seal between the valve andthe can, when this is in charging position, and also insures a return movement and perfect engagement on the seat 22 when the can is removed.

Another important feature of the invention is the construction which permits the syrup to be conveyed from a distant storage or source directly to the cans without being exposed to air or conditions which might cause contamination of the syrup. The machine as a whole is simple-and compact in construction and as intermittent movements are entirely eliminated it is obvious that comparatively high speed and large capacity is obtained The materials and finish or" the several parts of the radiator are such as the experience and judgment of the manufacturer may dictate,

I wish it understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims and that ll'do not wish to limit myself to the specific design and construction here shown.

Having thus described my invention, what I claim and desire to secure by Letters Patent is 1. In a can filling machine, a charging valve, a fluid inlet, means to mount the valve for reciprocal movement, and a unitary flexible tube rigidly connected at its ends to said inlet and to the valve.

2. In a can filling machine, a charging valve, a fluid inlet, means to mount the valve for reciprocal movement, and a rubber flexible tube rigidly connected at its ends to said inlet and to the valve.

3. In a can filling machine, a casing, a head at the casing top having a hollow extension projecting into the casing, a charging valve having a stem slidable in the lower end of the casing and having a hollow extension projecting into the casing, means to supply fluid to the extension of the head, and a rubber tube received over said extensions at its respective ends and rigidly connected to each.

4. In a can filling machine, a valve comprising a cylindrical casing, a head member in the upper end of the casing, a venting tube secured in and extending centrally through the head and easing, a head member secured on the lower end of the tube below the cylindrical casing, said last named head member having a valve seat formed on its upper side, a valve having a stem slidably mounted in the lower end of the cylindrical casing and adapted to normally engage the seat, said valve consisting of a cylindrical portion entering the lower end of the cylindrical valve casing and a flanged horizontal portion positioned, below the cylindrical valve casing, and a flexible tube secured at its upper end to the first mentioned head and at its lower end to the upper end of the cylindrical portion of the sliding v'alve.

5. In a can filling machine, a casing, a. hollow head in the casing at the top thereof, a charging valve having a hollow stem slidable in the lower end of the casing, means to supply fluid to the hollow head, a flexible tube rigidly connected at its ends to the head and stem respectively, and a coil spring surrounding the tube and engaging the valve to urge the latter outwardly.

In testimony whereof I have hereunto set my hand'in the presence of two subscribing witnesses.
